MINERS ACETYLENE-GAS LAMP.

Specification of Letters Patent.

Application filed September 4, 1915. Serial N o. 49,084.

'0 au whom t may concern Be it known that we, Jol-IN SUTCH, OLIVER Huron, and ALEXANDER BELL, subjects of the King of Great Britain, residing at Castlegate, in the county of Carbon and State of Utah, have invented new and use ful Improvements in Miners Acetylene-Gas Lamps, of which the following is a specification.

rlhis invention relates to miners acetylene gas lamps and it consists in the novel fea.- tures hereinafter described and claimed.

An object of the invention is to provide an improved lamp of the character stated, having t-.vo carbid chambers for the generation of gas, one of the said chambers being used at a time, and while the carbid in one chamber is being used, the other chamber may be refilled or replenished. In this manner, while one carbid chamber is being refilled, there is no necessity of extinguishing the light. Furthermore, the carbid chambers are provided with compartments intowhich the gas is delivered and burners communicate iviththese compartments, the said burners being in such close proximity with relation to each other that the gas emanating from one burner may be ignited by the iame at the other burner, and vice versa.

A further object of the invention is to provide a lampof the character indicated especially adapted to be used by coal miners, and with this object in view the parts are assembled in compact relation and it therefore may be, conveniently carried upon a cap or other part of the apparel. Furthermore, the device is simple in structure, and consequently may be manufactured at small cost and without requiring the use of expensive machinery.

In the accompanying drawings: Figure 1 is a vertical sectional view of the lamp. F ig. is a horizontal sectional view of the lamp taken through the burners thereof. Fig. 3 is a transverse sectional view of the lamp.

` The lamp comprises a cylindrical body 1 which is closed at its ends by means of detachable screw thread caps 2. The said caps are provided at their edges with outstanding flanges, and packings 3 of rubber or other suitable material are interposed between the said iianges and the end portions of the body 1. A partition 4 is disposed transversely across the body 1 midway between the ends thereof, and divides the said body ,into two carbid chambers or compartments. 'IA foraminous plate 5 is located in each of the said chambers or compartments at the upper part thereof and at the opposite sides of the partition 4, and filtering material 6, as for instance felt or blotting paper, is mounted upon the pla-tes .5. The said plates 5 serve as the bottoms of gas chambers 7 which are located in the upper portion of the body 1 and one at each side of the partition e'. Nipples 8 communicate with the said chambers and are located one at each side of the partition 4. Burners 9 are provided at the outer ends of the nipples 8. The said burners may be of any conventional type but preferably on the Bunsen type.

A water tank ,10 is ixedly mounted upon the body 1 midway between the ends thereof and tubes 11 depend` from the said tank and extend down into the chambers or compartments in the body 1 at the opposite sides of the partition 4. The upper portions of the tubes 11 open into the tank 10 whereby water may iiow from the said tank through the tubes into the body 1 of the lamp.

Parts of the upper ends of the tubes 11 extend from the bottom of the tank 10 to the top thereof, and the said tank is provided at its top and adjacent the said extensions with openings which are normally closed by screw threaded caps 19.. Rods 13 depend from the caps 12 and traverse the length of the tubes 11 and the said rods 13 are provided at their lower ends with enlarged heads 14' 'located just below the lower ends of the said tubes and adapted at times to close the lower ends of the tubes. The upper parts of the tube 11 serve as guides for the rods 13 to direct the same through the top of the tank 10 when the parts are being assembled. The tank 1 is provided at its top with a water inlet opening 15, which is normally closed by a cap 16.

In operation the caps 2 are removed and carbid is placed in the body 1 at the opposite sides of the partition 4. The cap 16 is swung from over the opening and the tank 10 is filled with water. While this is being done, the heads 14 are brought to closed positions against the lower ends of the tubes 11. When it is desired to generate gas in the lamp, one or the other of the caps 12 is turned whereby the rod 13 connected with the said cap is moved longitudinally and the head le is moved away fromthe lower end of the tube l1, through which the said rod passes. Thus, the Water may flow from the tank l0 down through the tube ll into the carbid at one side ot the partition d, lVhen the water comes in contact with the carbid the acetylene gas is generated, and this gas passes up through the openings in the plate 5 and filter 6 and enters the chamber 7 just above the said filter. From the said chamber the gas passes out through the connected nipple and burner and may be ignited at the burner` `When the carbid in the compartment becomes eX- hausted or ineilicient for the purpose of generating gas, the other cap l2 is turned whereby.7 the water is permitted to enter the other carbid compartment, and thus the gen eration of the gas continues at the opposite side et the partition and as this gas emanates through the other nipple and burner it is ignited by the Haine from the lirst mentioned burner as it passes out of the second men` tioned burnei.

lt is apparent that while the lamp is burning it may be turned on its side and one or the other of the carbid compartments may be replenished with carbid, hence the burning of the lamp may be maintained for an indefinite period of time and one who is `using the lamp is not compelled to lose time owing to the tact that he will be in darkness during that interval at which the lamp is being replenished with carbid.

Having described the invention what is claimed is An acetylene lamp compris-ing a body, detachable caps closing the ends thereof, a partition located in the body and disposed transversely thereotl and dividing the saine into two carbid compartments, toraminous plates located in the said compartments at the opposite sides of the partition and forming the bottoms oit' gas chambers, iiltering material supported upon the plates and located in said gas chambers, burners con nected with the gas chambers at points above the filtering materials and located in close proximity with relation to each other and at opposite sides of the partitions, a. tank mounted upon the body, tubes depending from the tank and entering the body at the opposite sides of the partition, caps screw threaded in the top of the tank, rods attached to the caps and traversing the lengths of the tubes and enlarged valve heads carried at the lower ends ot the rods and adapted to close against the lower ends of the tubes.

In testimony whereof we allix our signatures in presence of two witnesses.
